Tennis Elbow (Lateral Epicondylitis)

Tennis elbow, or lateral epicondylitis, is degenerative tendon pain at the outside of the elbow.

Tennis elbow, or lateral epicondylitis, is degenerative tendon pain at the outside of the elbow. It can result from racquet sports, gripping, lifting, tool use, desk work, cooking, weight training, or a rapid increase in activity. It is not an acute tendon rupture.

Most patients improve without surgery. Treatment focuses on reducing excessive tendon load, rebuilding wrist and forearm strength, and correcting work, sport, or equipment factors that continue to irritate the tendon. Bracing and selected procedures may help symptoms, but they do not replace rehabilitation.

Dr. Knudsen evaluates the elbow to exclude radial tunnel syndrome, instability, arthritis, cartilage injury, neck-related pain, or a more substantial tear. Surgery is reserved for persistent, substantially limiting symptoms after a prolonged and well-supervised nonsurgical program.
